A novel approach for approximating the average field diffracted from a double-layered dielectric wedge with Gaussian rough inner wedge face

This article studies the phenomenon of diffraction from a double-layered dielectric wedge that has roughness on the inner wedge face. For realizing the practical significance of this study, a hilly terrain may be imagined where the hills act as obstacles in the path of radiowave propagation and they are covered with snow or forest. Since generally, the hill surfaces are rough, these snow or forest covered hills can be approximated by double-layered dielectric wedges with a rough inner wedge face. Hence, this novel approach for approximating the average field diffracted from such wedges will be helpful to those involved in propagation channel modeling, especially for hilly and mountainous terrain.
